What is it that happens inside my body when I get anxious/anxiety about something? Chemical relations maybe that triggers a condition that in the past has been diagnosed as cyclic vomiting syndrome. When I get anxious my heart rate increases, I get sweaty, my saliva increases and then I start uncontrollable vomiting. Which in some cases can last days. I can't hold any food or drink don't. I don't even feel like eating. I do drink fluids so I actually have something to spew. The only way I have been able to stop the spewing is by some form or relaxant, ie Valium, phenergan. Normal nausea medication has no effect; maxelon. My question is, what is my body doing this? And which part of my body is creating this; I really don't feel I can stop this; people have said it is all in my head and if I can calm my body down and relax I should be able to stop it, but this doesn't appear to be the case. I wanted to know what is reacting with what to cause this and is it possible to stop it before it happens. I can feel it is going to happen about 1-1.5 hours before it does. Any thoughts?
